This course provides information about air pollution control efforts since the passage of the Clean Air Act and places in perspective various issues that have arisen since passage of the act--significant deterioration, maintenance of standards, indirect source review, and transportation controls. Court decisions affecting these issues are cited and discussed. The course consists of four units or modules. Each unit consists of an audio cassette tape and supplementary printed materials, designed to be followed while listening to the recorded presentation. The format is designed to be self-instructional, but could be used by groups. Questions are included at the end of each section of each unit. The units of the course are as follows and may be taken in any sequence: (1) National Ambient Air Quality Standards and State Implementation Plans, (2) Federal Standards for Stationary and Mobile Sources, (3) Maintenance of National Ambient Air Quality Standards, and (4) Significant Deterioration of Air Quality.
